T 0 (LZZ whom it may concern:

Be it known that I, FRnDnRIo BARR, a citizen of the United States, residing at 255 Eighth street, Brooklyn, county of Kings, State of New York, have invented certain new and useful Improvements in Bread-Mixers, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to furnish a bearing-bar for a dough-mixing stirrer, which bar and its attachments may be formed of sheet metal and adapted to fit upon or engage the edge or handle of mixing-pans of various diameters and to furnish a construction in which all the parts may be readily separated to facilitate the cleansing of the same after they have been used.

The invention embraces a bearing-bar having both ends adjustable to fit mixing-pans of various diameters, means applied to the ends of the bar for engaging them with the handle or edge of the bread-pan, a socket of particular construction upon the bearing-bar With a bearing secured detachably in the socket to support the spindle of the stirrer, and a stirrer-spindle adjustable vertically in the bearing to suit pans of various depths and provided with a clamp-collar for supporting it in its adjusted position.

The details of construction will be understood by reference to the annexed drawings, in which- Figure l is an elevation of the apparatus with the mixing-pan in section. Fig. 2 shows the upper side of the bearing-bar; Fig. 3, the under side of the same; Fig. 4, a longitudinal section of the same. Fig. 5 is a cross-section on line 5 5 in Fig. 2. Fig. 6 is an elevation of the socket; Fig. 7, a side view of the same, and Fig. 8 a view of its bottom end. Fig. 9 is a plan of the stirrer and its hand-crank, and Fig. 10 an elevation of the same at right angles to the view shown in Fig. 1. Fig. 11 shows a lever for locking the slide upon the flange of the pan.

The body a of the bearing-bar is shown formed of sheet metal with inwardly-turned flanges Z) upon its edges and slides 0, of sheet metal, fitted within such flanges and provided at the ends with hooks d to embrace the edges 6 of the mixing-pan f.

Both ends of the body a are provided with adjustable slides, so that the bearing-bar may be adapted to fit pans of different diameters and retain the bearing in the center.

The body a is provided with slots 9, and screws h are inserted through the slots into the slides to adjust them upon the body. An in wardly-tapering or conical sockett' is shown fixed upon the center of the body a and formed with notch j in one side, and a notch in is eX- tended from the notch j outward to the edge of the body a. The bearing Z is of tapering form to fit tightly in the socket and is provided with a rib m at one side to fit the notch j. A lug m extends downward from the rib m through the bearing-bar and is provided with a notch 12 upon its outer side to receive a tongue 0, formed upon one of the slides to lock the bearing in the socket when the slide is suitably adjusted for use upon the pan. The tongue forms a lock to lock the bearing in the socket. The tongue is formed at one side of a slotp in the slide, having a notch 3; extended to the edge of the slide, which coincides with the notch in in the body a when the slide is pushed inwardly with the screw 72, at the inner end of the slot g.

For regulating the adjustment of the slides to bring the bearing in the center of the mixing-pan a scale is formed at the side of the slot 9 upon the body a to coincide with the inner end of the adjacent slide when properly adjusted.

The device as illustrated is adapted for use with pans from fourteen to eighteen inches diameter, and five marks are shown upon the scale, (marked 14 15 16 17 18,) which indicate the adjustment of the inner end of the slide for pans of such size. Only one of the slidesneeds to have the scale applied to it, as this slide operates to set the bearing in the center of the pan, corresponding to the number marked upon the scale, and the opposite slide can be set in and out for the purpose of securing the bearing-bar upon the pan and removing it therefrom Where the stirrer is used habitually with the same bread-pan, it is obvious that the slide governed by the scale can be secured permanently in the proper position for use with such pan, and only the opposite slide needs to be moved at all in applying the bearing-bar to the pan. Such a clamping of one slide is indicated by the provision of the scale, which shows the proper adjustment of one slide for continued use with one pan. scale thus operates to bring the bearing automatically to the center of the pan without adjusting both of the slides and without any trial or measurement, while the provision of The IIO

slides at both ends of the bearing-bar adapts it for use with pans varying widely in size.

The stirrer is formed witha spindle g, having a lateral oifset q, from which an armris curved downward toareflexed prongr,which extends under the hand-crank 8 upon the upper end of the spindle. The prong 1" extends parallel with the bottom of the pan f and can be adjusted at a suitable distance above the same by a set-screw collar t, which rests above the top of the bearing Z'. the spindle, and the stirrer are made of one piece of round bar-steel, and the bearing Z is placed upon the spindle, with the collar 2?, before the hand-crank is bent, and thus lies between the hand-crank and the otfset q.

When the slots 9 and 7c are coincident, the shank of the spindle above the oifset q can he slipped sidewise through the slots into the center of the socket and the bearing then dropped into the socket and locked therein by the tongue 0. Such locking is effected when the slide is pulled outward, which is necessaryto fit even the smallest-size mixingpan, (about fourteen inches diameter,) and the bearing can be detached from the socket to facilitate the cleansing of all the parts after use by pushing the slide inward again.

In Fig. 1 the slide at the right-hand end of the bearing-bar is shown with its end bent backwardly and formed with three transverse grooves or steps a, which are adapted, respectively, to fit beneath the handles f upon pans of different sizes. The slide is made of sheet metal, and the transversely grooved portion of the slide is of elastic character. owing to its reflexed position upon the end of the slide, and it can therefore be inserted beneath the handle and pried up against the same to hold the slide firmly.

The slide at the opposite end of the bearing-bar is provided with an inwardly-turned hook e, which fits beneath the flange rZof the pan at the opposite side, and a hole a is formed in the slide adjacent to the hook to receive a stud it upon a bracket-clamp v. which draws that edge of the pan downwardly upon its supporting-table T.

The stud u is formed upon a vertical standard w, which is adjustable by means of a screw 1&2 upon the slotted post of the-bracket-clamp n, and the stud is projected downwardly from an arm w upon the top end of the standard. The standard is so adjusted upon the bracketclamp that when the screw 4) of the clamp is tightened the arm w may press upon the upper side of the bearing-bar and clamp the pan firmly upon the table, while the stud passing through the hole at contacts with the inner wall of the panto hold it securely in place.

Instead of forming one of the slides with the steps a to engage the pan-handle, both slides may be formed with the hooks d, and when the slots are pressed inwardly to engage the flange 6 they may be held in such engage- The hand-crank,

ment by a lug having lever pivoted upon the under side of the bar to press upon the inner wall of the pan. Such a lug is shown in Fig. 11 with a lever m pivoted upon the slide 0 by a detachable screw y, the lug pressing against the inner wall of the pan when the lever is turned lengthwise of the slide, as shown in Fig. 11. A series of holes 3 permit the lug to be adjusted upon the slide.

The socket is. like the body a, formed of sheet metal stamped into the desired form and provided upon the lower end with three studs 2, (shown in Fig. 3,) fitted to holes in the bearing-bar in which they are riveted flush with the under side of the bar to hold the socket thereon, as shown in Figs. 4 and 5. The only parts not formed of sheet metal are the bearing Z and the bracket-clamp o and the stirrer,

which is formed from a straight round bar. The whole construction is made readily and cheaply by the aid of suitable tools and furnishes a durable and convenient form of doughmixing device, in which the mixing parts can be readily separated from one another, so as to cleanse them thoroughly after using.

It will be observed by reference to Figs. 1, 9, and 10 that the arm r curves not only downwardly but laterally from the end of the offset 9' and is connected with the prong r by a reflexed curve, all of which curves cause the stirring-rod to traverse different parts of the dough and to mix the same in a very effective manner.

The reflexed curve which joins the arm 9 and the prong 0" forms a loop which when the stirrer is rotated gathers the dough together and mixes it in a manner entirely different from the stirrers, which extend downward from the spindle 'in a simple vertical plane.

Figs. 1 and 9 show the prong 7* extended beneath the crank 8' parallel with the same, so that the offset 9 is at right angles to the crank, which arrangement of the prong 0pposes the crank most effectively to the resistance of the dough to the stirrer; but'the support of the spindle in the bearing enables the crank to rotate the stirrer in whatever position the crank be bent from thespindle.

The construction of my hand-crank s and stirrer in one piece with the spindle q necessitates the fitting of the bearing Z to the spindie before the rod is finally bent, and in order to separate the spindle from the bearingbar to readily cleanse the same it necessitates a bearing-bar with a notch in the side and a bearing which can be secured upon the bar detachably. These features are cheaply provided in the structure shown in the drawings, and my invention is distinguished from previous constructions in this peculiarity of the bearing and of the bearing-bar.
